It is thought the pair, who worked in a children’s home, were about to reveal information about the alleged Westminster paedophile ring. The shock news came after it emerged Scotland Yard is probing a “possible homicide” at a block of luxury flats popular with MPs.

The Dolphin Square apartments in Pimlico, London, are said to have been used for child sex abuse “parties” involving senior politicians, spy chiefs and leading military and legal figures in the 1970s and 80s.

But an MP now claims the alleged sex abuse ring may have been linked to at least two more murders.John Mann, 54, inset above, said: “The deaths of these people are linked to a children’s home at Lambeth and concern two adults that I believe were murdered.

“They were both potential whistle- blowers who knew about the paedophile activities of senior political figures and well-known individuals.

“I have given the details to the police before but now they seem to be taking the allegations seriously and I have been interviewed and expect to be interviewed again soon.

“The information has come from various sources including alleged victims of this paedophile ring. They have also told me of many suicides by children who were abused and humiliated.”

Met Police detectives are currently searching for the infamous “Dickens Dossier” – the missing file detail- ing allegations of a Westminster child sex ring in the 1980s.

Mr Mann, Labour MP for Bassetlaw, Notts, added: “Since the Dickens Dossier and the activities of paedophile MP Cyril Smith have been highlighted, victims have started coming forward.

“At first I heard from about eight victims but now dozens of people are coming forward to give evidence. “They are naming names but they are not all politicians or famous people.”

The Government set up an inquiry into claims of a top level cover-up of VIP paedophiles but Home Secretary Theresa May has struggled to find a chairman.

Two people asked to lead the inquiry – lawyer Fiona Woolf and retired judge Baroness Elizabeth Butler-Sloss – have been forced to quit over their links to the Establishment.
